The contentsof the expandable internal compartment are preferably concealed fromview when either of the adjoining compartments adapted for carryingbusiness items is opened. The business case can be constructed in wholeor in selected part of a waterproof material or can be treated in amanner to protect one or more of the interior compartments from water.

[0028] In a preferred embodiment, the business case of the presentinvention comprises a plurality of internal compartments and/or storagepockets. In the preferred embodiment of the present invention, a housingstructure is provided including a first exterior sidewall and anopposing second exterior sidewall, each sidewall being fixedly attachedto a lower bottom panel and an opposing upper top panel, a first sidepanel and an opposing second side panel that forms a business case. Thefirst sidewall and the second sidewall are attached to the lower panel,upper panel, first side panel and second side panel by common methodsknown in the art for attaching the materials together, such asstitching. Further, a plurality of fastening means such as zippers,snaps, hook and loop fasteners and/or buttons are provided to allow theuser to access the internal compartments of the business case andsubsequently rejoin the members of the case after opening it.

[0029] In one preferred embodiment, the business case includes an firstexternal compartment that can be expandable and serves a variety offunctions. This first external compartment is internally separated fromthe rest of the adjacent compartments of the case. Access to this firstcompartment can be via a rejoinable opening, such as a zipper, on thetop and adjoining sides of the compartment. The first externalcompartment can provide for storage of various materials, such as pens,papers, computer disks, and the like. Furthermore, the first externalcompartment can comprise a plurality of specialized storage compartmentssuch as an expandable compartment, pen and pencil sleeves and a pocketmember dimensioned to secure memory disks for computers, pocketcalculator, and other small stationery items.

[0030] A second outside compartment is provided appropriately padded foruse as a storage compartment for a notebook or laptop computer or likedevice. It is well known in the art to provide such a compartment forsecurely and safely carrying a portable computer so as to protect it andminimize shock to the device upon impact if the case is mishandled andforcibly comes in contact with a rigid object. An interior dividing wallis provided to separate the second internal compartment from the otherinternal compartments to insure that the notebook computer is protectedfrom items in the other internal compartments. Specifically, it is wellknown in the art to provide sufficient padding and cushioning of foam orlike material on the interior surface of the second internal compartmentto prevent damage to the sensitive electronic equipment carried in thecompartment. The computer can be secured in the second outsidecompartment by means of a fastening strap, hook and loop fasteningstrap, cradle system, elastic member or other like means known in theart. In addition, additional storage space is provided in the secondoutside compartment for the storage of other business related items orcomputer accessories.

[0031] A third internal compartment, intended for use as a storagecompartment for clothing and for other personal items, is providedcomprising an expansion gusset. A wrap-around zipper, or the like, isprovided to secure the third internal compartment in a collapsedposition. Thus, in the closed position (i.e., zippered), the wrap-aroundzipper maintains the business case in a low profile configurationthereby limiting the internal volume of the third internal compartmentso that only the expansion gusset is disposed therein. In the open orun-zippered position, the wrap-around zipper permits the expansion ofthe gusset thereby allowing the expansion of the interior volume of thethird internal compartment. The interior volume of the third internalcompartment is of sufficient size, when expanded, to provide space forthe storage of overnight clothing and personal care products used duringtravel. Specialized storage compartments can be disposed therein toallow the user to neatly and efficiently store toiletries and the like.A protected, waterproof compartment can be provided to prevent thetoiletries from leaking onto the items in the third internal compartmentor any of the internal compartments of the business case. In addition, aplurality of elastic bands, buckle-type straps or other retaining meansthat are well known in the art to facilitate the packing of clothingitems and personal toiletries are optionally provided. Once the clothingis removed from the business case, the overall size of the case canagain be minimized by securing the wraparound zipper, thereby,substantially reducing the interior volume and re-establishing thelow-profile configuration of the business case. Access to the storagevolume is provided through one of the common interior adjoiningsidewalls of an adjacent compartment, as will be explained below.

[0032] A fourth outside compartment is provided comprising a zipperedsecond sidewall for enclosing a file folio therein. The file folio,comprising a plurality of pockets, can be of the type commonly used inthe art for the storage of file folders, documents and similarmaterials. The file folio can be attached in the interior compartment ofthe business case in a permanent manner or a removable manner. Aplurality of release straps are provided and affixed to the file folioand to the interior wall of the fourth compartment. The release strapsfastened by snaps, hook and loop fasteners, a zipper, or the like, serveto maintain the low-profile configuration. Upon opening of these straps,the file folio is released from a soft interior dividing wall allowingaccess to the interior of the central expandable volume of the thirdinternal compartment. The soft interior dividing wall is provided toisolate the personal items from view when either the file folio or theother of the adjacent internal compartments is opened. When access tothe interior of the third internal compartment is desired, the zipperextending around three sides of the fourth outside compartment iscompletely opened and the interior straps securing the file folio inplace are released, thereby allowing the file folio to be moved away andfor the two sections of the case to be laid flat in a joinedside-by-side position.
